20110122532WRITE HOLE OF A HEAD SLIDER IN A HARD DISK DRIVE - A head slider for supporting a head over a magnetic disk in a hard disk drive, and a method of making the head slider are disclosed. The tail section of the head slider has a deep write hole that may improve the altitude performance of the head slider by minimizing fly height variations at high altitudes (i.e., altitudes above 3000 m) or in low atmospheric pressure environments. The write hole prevents the fly height from changing. Additionally, the write hole limits the amount of lubricant that will flow over the ABS.05-26-2011

20100053816HEAD-SLIDER, HEAD-ARM ASSEMBLY INCLUDING THE HEAD-SLIDER, AND HARD-DISK DRIVE INCLUDING THE HEAD-ARM ASSEMBLY INCLUDING THE HEAD-SLIDER - A head-slider which is configured to fly above a magnetic-recording disk. The head-slider includes a disk-facing side, which faces the magnetic-recording disk. The disk-facing side includes a plurality of surfaces including at least: a step bearing surface; a rail surface, which protrudes toward the magnetic-recording disk and is configured to exert a positive pressure; a deep-recessed surface, which is formed deeper than the step bearing surface and is configured to exert a negative pressure; an extended lateral surface, which is formed at substantially a same depth as the step bearing surface and disposed outside the deep-recessed surface in a width direction of the head-slider; and, an extended rear surface, which is formed at substantially the same depth as the step bearing surface and disposed at a trailing edge of the head-slider, and contiguous with the extended lateral surface.03-04-2010
20110058275DISK DRIVE INCLUDING HEAD-SLIDER CONFIGURED TO SUPPRESS LUBRICANT DROPLET ACCUMULATION - A disk drive. The disk drive includes a disk and a head-slider. The head-slider includes an air-bearing surface. The air-bearing surface includes a trailing-edge rail surface, an inner trailing-edge pad, and an outer trailing-edge pad. The pad surface of the outer trailing-edge pad includes a straight outer edge slanting outward; and, the angle of the outer edge with respect to the longitudinal direction of the head-slider is β03-10-2011
20110069408DISK DRIVE, HEAD-SLIDER AND METHOD FOR CONTROLLING CLEARANCE OF A READ ELEMENT AND A WRITE ELEMENT IN THE DISK DRIVE - A disk drive. The disk drive includes a disk, a head-slider, a moving mechanism, and a controller. The head-slider includes a read/write element, a first heater element, a contact pad, and a second heater element. The read/write element includes a read element configured to read user data from the disk, and a write element configured to write user data to the disk. The moving mechanism is configured to support and to move the head-slider. The controller is configured to control the second heater element to control contact between the contact pad and the disk, and is configured to control clearance between the read/write element and the disk by using the first heater element with the contact pad in contact with the disk.03-24-2011
20110149430Magnetic Head Slider and Magnetic Disk Drive - A magnetic head slider is disclosed. The magnetic head slider includes a slider substrate and a laminated magnetic head element on the slider substrate. Additionally, the laminated magnetic head element includes a magnetoresistance effect element and a recording magnetic pole formed in a layer higher than the magnetoresistance effect element. A first thin-film resistor heater element is formed in a position further from an air bearing surface than the magnetoresistance effect element and the magnetic recording pole and a second film resistor heater element is formed in a layer lower than the first thin-film resistor heater element, and closer to the air bearing surface and the magnetoresistance effect element than the first heater element. A thin-film resistor sensor element is formed in a layer higher than the second thin-film heater element and closer to the air bearing surface than the second heater element.06-23-2011
